Longi Solar PV Panels & SMA Inverters
At MarVal Power, we pride ourselves on delivering high-quality energy solutions and technology. Our installations’ effectiveness is due to SMA inverters and Longi solar panels, which provide our clients with the best value and performance.

What are SMA Inverters?
SMA inverters are the backbone of solar energy systems. They play a crucial role in converting direct current electricity (DC), which solar panels generate, into alternating current electricity (AC), which powers many household appliances and is fed into the electrical grid.
SMA inverters have high conversion efficiency and can improve system performance. Solar energy captured by the panels is converted into usable electricity. SMA’s monitoring service additionally permits advanced performance tracking, catching possible system issues or improvements early on.
What are Longi Solar Panels?
Longi solar panels are renowned for their advanced energy efficiency, generating large amounts of electricity. They are designed to withstand various environments, including Ireland’s rainy days, and can be seamlessly integrated into different installations, whether it’s a school or an office building.
Combining SMA inverters and Longi solar panels creates a reliable, durable, and efficient energy system.
